Finger pulse oximeters are usually found at doctors’ offices and hospitals, but what you may not know is that you can also buy one to use at home. There are several different brands and designs available so that you can easily check your blood oxygen saturation levels from the comfort of your home.

While the COVID-19 pandemic has led to a renewed interest in pulse oximeters for home use, there are many other reasons why you might consider investing in your own device to have on hand. For example, conditions like hypoxemia can result in low blood oxygen levels, and having a finger pulse oximeter at home could provide better peace of mind.

If you’re thinking about purchasing an at-home finger pulse oximeter, it’s important to discuss with your doctor when you should use it, how to interpret the results, and when to seek medical care.

Finding the right device for your needs may take some time, and you may be wondering what the difference is between all of these different devices. So, to help make your search a little easier, we’ve compiled our top picks of the eight best finger pulse oximeters so you can start tracking your levels quickly and easily from home.

  • Best for multiple display options: Innovo Premium iP900BP Pulse Oximeter
  • Best for ease of use: Walgreens Pulse Oximeter
  • Best for both children and adults: CVS Health Portable Pulse Oximeter
  • Best for portability: Metene Fingertip Pulse Oximeter
  • Best for budget: Contec CMS50DL Pulse Oximeter
  • Best for easy to read results: ChoiceMMed Pulse Oximeter

Pulse oximeters are most commonly worn on your finger and are completely painless to use. These devices have light-emitting diodes, or LEDs, on the inside of the probe that can send small beams of light through your finger to track the amount of oxygen in your blood. The light shines through the tissues of your fingertip, and the sensor on the other side picks up the light that comes through.

Finger pulse oximeters can then measure how much light comes through your finger to estimate how many of your red blood cells are carrying oxygen. This type of reading is called oxygen saturation, or SpO2, and the results display as a percentage.

Readings should typically fall between 95 and 100 percent, with readings at 92 percent or below potentially indicating that there isn’t enough oxygen in your blood. If your finger pulse oximeter reading is below 90 percent, try testing again — in case there was a testing error — or consider contacting your doctor.

The American Lung Association also says that your oxygen saturation level should be over 90 to 92 percent. Checking that your oxygen saturation level is above the recommended level can help you determine whether you need to seek emergency medical attention. Such cases may be brought on by acute illnesses, like pneumonia, or flare-ups of chronic conditions, like asthma. Oximeters may also be useful for extreme sports.

Signs of low blood oxygen levels
  • difficulty breathing
  • fast breathing
  • shallow breathing
  • sucking in the stomach when breathing
  • confusion
  • difficulty waking up
  • blue-tinged lips or face

No matter what your finger pulse oximeter says, seek emergency medical attention if you or your child has any signs of low blood oxygen levels, or hypoxemia.

Here, we focused on over-the-counter (OTC) oximeters made to be used at home and by people who aren’t healthcare professionals.

Keep in mind that these consumer devices aren’t reviewed and regulated by the Food and Drug Administration (FDA) in the same way as prescription pulse oximeters. They’re meant for spot checks and are designed to be smaller, cheaper, and easier to use. Some may also have special features that suit your day-to-day needs.

Overall, we chose the best finger pulse oximeters based on:

  • ease of use
  • overall cost
  • accuracy rates
  • display options
  • age recommendations
  • comfort and size
  • customer reviews and ratings
  • clinical testing

  • If you need a pulse oximeter for the whole family, make sure it fits a child’s small fingers.
  • Check to see if the device is FDA-approved, or tested to ensure accuracy.
  • Take a look at the product’s ratings and any customer reviews.
  • Most finger pulse oximeters are for spot checks. If you need continuous monitoring, ask your pharmacy about medical-grade oximeters for at-home use.

At this time, the most accurate ways to measure blood oxygen levels are through pulse oximeters or arterial blood samples.

Speak with your doctor or another healthcare professional for more information on monitoring your blood oxygen levels.

  • Make sure your hands aren’t too cold, hot, wet, or sweaty.
  • Keep your hand and fingers still. Don’t move while you’re taking the reading.
  • Avoid placing the pulse oximeter probe on a fingernail that has nail polish or on tattooed skin.

How accurate are finger pulse oximeters?

At-home devices are designed to be easy to use but may not be as accurate as medical-grade devices. The accuracy of a reading can also depend on the device and whether you’re using it properly.

But these at-home devices can give you a good estimate of your blood oxygen saturation levels. In fact, a 2021 study found that while the accuracy of some at-home oximeters fell short of the ISO standards required for clearance by the FDA, they could still accurately rule out the possibility of hypoxemia.

According to a 2016 study, some pulse oximeters that are not approved by the FDA can produce large errors (an average of 6.3 percent lower, or 4.3 percent higher, than the actual result) with blood oxygen saturation measurements.

What can affect pulse oximetry readings?

A pulse oximeter reading is an estimate and may not always be accurate. As the light travels through your fingernail and tissue, several things can affect the accuracy of the SpO2 reading, including:

  • Skin color. Skin with more pigment may cause some pulse oximeters to give inaccurate readings. A 2020 study found similar supporting results.
  • Conditions that cause circulation problems. Poor blood circulation in your hands and fingers may cause lower readings.
  • Cold hands. Having cold hands may cause lower readings.
  • Wet skin. Water or sweat on the skin may reflect the light and affect the measurement.
  • Thick fingernails. Thick nails can block the light penetration and may cause lower readings.
  • Fingernail polish. Black, blue, and green nail polish may cause significantly lower readings.
  • Bruises or tattoos on the fingertips. Both may cause inaccurate readings. Try choosing a different finger or limb for a more accurate reading.

I have dark skin. Can I still use a pulse oximeter?

The short answer is yes. While the FDA has found that pulse oximeters may have a higher risk of inaccurate numbers when used on skin with more pigment, these devices can still help you monitor your health.

If you want to monitor your blood oxygen levels, watch for trends in your readings, like if the readings show percentage levels that decrease or drop.

There are many finger pulse oximeters available for at-home use, and knowing how you will use the device will help inform your decision. While they may not be 100-percent accurate in their readings, these oximeters could still be a very helpful tool if you’re tracking your blood oxygen level and pulse for exercise or personal use.

But if you need to track your blood oxygen levels for medical reasons, consider looking for medical-grade, FDA-approved devices, or talk with your doctor or local pharmacy so they can recommend the most accurate finger pulse oximeters.
